It would be nice if we could use self closing components:

Thanks!

I looked into this spec(i.e., Self-closing tag). It seems to me that the custom element should have a closing tag:

But I could not find the official specifications. (W3C / WHAT-WG)

I guess major browsers will inject closing-tag automatically on their HTML parser. (I tried this phenomenon using by non-closing

tag. <div><p/></div> should be <div>< p></p></div> automatically)

In spear case, a parser is node-html-parser, So spear is dependent on this library.

If we support self-closing components, we should implement the pre-convert process, like auto closing-tag injection.

our parser can't handle it, so I think its ok to leave as it is for now. Its no problem, just small details for the person who is used to frameworks

We can parse it if we have preprocess which injecting close tag.
